1. The quote that begins the chapter is from Stuart L. Pimm's book The Balance of Nature? Ecological Issues in the Conservation of Species and Communities(Chicago: University of Chicago Press (1991), p. 4.
2. Several good books each present a fine overview of the various aspects of astronomy and cosmology discussed in this chapter. For example, see F. Adams and G.
